If a scheduled or a manual recording fails or the unit won't record, review the following items.
Check Storage Free Space
Be sure the selected UltraNEXUS-HD storage destination is not full and has sufficient free space for new recordings. You can check the UltraNEXUS-HD storage space on the Dashboard page of its web interface or the Storage Manager window (right side bottom) of the WinLGX software.
Reboot
If the UltraNEXUS-HD does not display an error message but appears to try and record, and creates a recording file of 0 KB in size, then reboot it (see instructions below). After the reboot, perform a recording test. Often, when the input signal is unstable or has changed, the input of the UltraNEXUS-HD needs to be re-initialized in order to lock on to the new signal.
There are three ways to reboot the UltraNEXUS-HD:
- In WinLGX go to the tools menu, select Controller, and click the Reboot button at the bottom of that window.
- In the WebNEXUS browser interface, go to the System Settings page on the maintenance tab and click the Reboot button.
- Or, from the front panel (confirm you are at the date and time display), press and hold the green check button for about eight seconds, then let go (On an UltraNEXUS-HD Blade, press the joystick straight in). When the date and time appear, the reboot is complete.
NOTE: If a reboot gets the recording working and this happens often, you should try scheduling a weekly reboot. Here's a link to the tutorial: Scheduling a Reboot
Check the Events Log
Check the UltraNEXUS-HD's Events.log for any warn or failed log entries at the date and time of the scheduled recording.
If it displays an error message or log entry about the video signal being Unlocked, Not detected, or Not supported, then either there is/was no video signal present at the SDI input of the UltraNEXUS-HD, or it is a video signal type that the UltraNEXUS-HD cannot record.
Error Code 533
If you encounter: Error 533 New file exists (overwrite mode set to NEVER)
- This indicates a recording was attempted with the same file name of a file that already exists in the storage.
- You'll need to either change the desired filename or change the overwrite mode to Always, but be aware that this will allow it to overwrite a file if it already exists.
Error Code 500
Make Sure the Video Signal is Present at the SDI Input
If you encounter: Error code 500 record failed, supported video standard not detected (UNLOCKED)
-
Make sure the video signal you wish to record is connected to the SDI input of the UltraNEXUS-HD.
- If using an external switcher, make sure the desired video signal is switched to the SDI input of the UltraNEXUS-HD.
Make Sure the Video Signal is Correct
If you encounter: Error code 500 record failed 3G-SDI is not supported (1080p60)
Make sure the signal is one that the UltraNEXUS-HD can record.
You can check if it's locking to a video signal from the front panel. Press the up-arrow button until the display says "SDI IN:" You can also check the SDI In status on the Dashboard page of the UltraNEXUS-HD's web interface. It will show one of the following:
- "Unlocked" - this means it doesn't sense a signal.
- "1080i 60" - this means it sees a 1080i signal that it can record.
- "720p 60" - it sees a 720p signal that it can record.
- "480i 30" - it sees a 480i signal that it can record.
Any other type of signal is not supported and you'll need to check your source device and set it to one of the 3 supported types above or get a converter.
Example Control Panel error message:
“500 Record Failed 3G-SDI is not supported (1080 60p)” (Or a similar “unsupported” message)
The UltraNEXUS-HD can only record 1080i, 720p, or 480i signals. It cannot record 1080p (3G). You will need to check your source's signal output setting and set it to one of the supported formats above. If using a signal converter, confirm its output is set to one of the above acceptable signals.
Example of error log entry:
“Dec 19 17:50:35 dm8168 local3.warn mpeg_mon: Record of file /media/Vol1/mpeg/TestREcord5.m2t FAILED, supported video standard not detected on input”
Audio Issues Causing Record Failure:
Missing SDI Embedded Audio
If using SDI Embedded audio, ensure there is audio in the SDI signal.
- If using SDI embedded audio, if there is no audio in the SDI signal it will not record (muted audio is ok).
- Check for SDI audio present in the web interface Dashboard page (Lower right corner).
- It will say “SDI Audio: Present” or “SDI Audio: Absent”
- If SDI audio is absent, you’ll need to check your cables, connections, or other devices upstream from the UltraNEXUS-HD that are providing the SDI audio signal to be recorded, to find out why there is no audio in the SDI signal.
Incorrect Record Preset Settings
If using Analog audio, make sure the record presets are set to Analog audio.
- Any recording will fail if the presets are set to Embedded when it should be Analog and there is no SDI audio.
- See the tutorial link: Adjusting Record Preset Audio Settings
Try a Loop Recording:
If you still are unsure where the problem lies you can do a loop recording test to isolate the problem.
- Loop the SDI output of the UltraNEXUS-HD to its’ SDI input with a single SDI cable.
- Play one of the sample Bars and Tone files (or any file you are sure plays correctly).
- Start a recording with the UltraNEXUS-HD using the Control Panel window.
- Wait for 30 seconds, then stop the recording.
- Play the recorded file in the software preview player in the WinLGX Storage Manager window (right-click the file and choose View) and see if the recording was successful.
- If the loop recording was successful, then the UltraNEXUS-HD is working correctly and you should check your cables, connections, or other devices upstream from the UltraNEXUS-HD that are providing the video and audio signal to be recorded.
